Concrete is a durable material that can last ages with proper protection. To maintain concrete surfaces in excellent condition, it’s essential to keep moisture out. That is where our high-quality concrete sealers shine. At E-Chem, LLC, we provide a wide variety of sealers for commercial, residential, industrial, and municipal concrete applications:

  • Basements and garage floors
  • Concrete decor for home interiors
  • Outdoor slabs
  • Airport runways
  • Bridge decks
  • Factory floors and support columns
  • Highways
  • Roadways
  • Concrete sealers are a smart investment. They extend concrete life, improve moisture resistance for underlying surfaces, prevent water damage and mold problems, and make concrete look more attractive.

    Sealers Explained

    It’s important to choose the right type of concrete sealer. If you’re unsure which one is the best fit for your project, these concrete sealer FAQs can help.

    Why Does Concrete Need to be Sealed?

    Concrete may seem solid and practically impervious, but it’s porous. That’s why water absorbs so quickly into bare concrete. Left alone, this moisture causes cracks and water damage. Freeze/thaw cycles are especially hard on concrete surfaces.

    Garage floors, driveways, and highways also have to deal with roadway chemicals, deicing salts, and dirt. A good concrete sealer keeps these contaminants on the surface and protects the concrete. For home and building interiors, a sealer is helpful because it prevents staining from accidental spills.


    What Types of Concrete Require Sealers?

    Virtually all concrete interior and exterior surfaces need to be sealed:

  • Regular concrete
  • High-performance concrete and UHPC
  • Reinforced concrete
  • Stamped concrete
  • Exposed aggregate
  • Concrete overlays
  • Precast concrete
  • Lightweight concrete
  • There are many sealer options for concrete types. Interior and exterior surfaces need different concrete sealers for the best results.


    How Can You Select the Best Concrete Sealers for Your Needs?

    In the same way that concrete comes in countless types, including high-performance and color-stained varieties, you can also get a concrete sealer with the specific characteristics your project needs. Here are a few factors to consider:

  • Penetrating or film-forming type
  • Low odor product
  • Drying time
  • Coverage
  • Ease of application
  • Estimated life of the product
  • Level of shine desired
  • Durability and scratch resistance
  • Cost
  • Certain concrete sealers are designed primarily for indoor applications, and others are better for exterior surfaces. Some products are specifically formulated for the food-service industry. You can even choose epoxy-based high-gloss concrete sealers that look phenomenal in automotive showrooms.

    How Long Should You Wait Before Applying Sealer to New Concrete Surfaces?

    Comprised of 100% solids and designed to be insensitive to moisture, this formulation is made from just two components. Its simplicity is matched by its versatility, with possible applications ranging from bonding for a skid-resistant overlay to patching concrete.

    How Long Do Concrete Sealers Last?

    The longevity of concrete sealers depends on the type you choose. Penetrating concrete sealers for outdoor use can last a lifetime. Acrylic sealers need to be reapplied every 1 to 3 years with normal wear and tear. Epoxy- and polyurethane-based concrete sealers usually last 5 to 10 years without issues.

    Urethane Seal

    EP75-SEAL URETHANE SEALER/HEALER

    EP75-SEAL is a highly penetrating, low-viscosity, two-component epoxy urethane sealer/healer offering longer life cycles than traditional epoxy polymer sealers. EP75-SEAL is designed to prolong the life of concrete by sealing cracks against moisture and chloride ion intrusion, with a rapid cure time that allows traffic to re-open quickly. It is also excellent for a low-viscosity prime coat prior to the placement of EPC-OVERLAY. Specific applications include bridge decks, parking decks, concrete floors, roadways, airport runways/taxiways, columns & beams in splash zones, and general consolidation of porous & dusting surfaces. EP75-SEAL is VOC compliant (<250 g/L).

    EP100-SEAL


    EP100-SEAL is a highly penetrating, 100% solids, two-component epoxy healer/sealer. EP100-SEAL is designed to prolong the life of concrete by sealing cracks against moisture and chloride ion intrusion, with a rapid cure time that allows traffic to re-open quickly. Specific applications include bridge decks, parking decks, concrete floors, roadways, airport runways/taxiways, columns & beams in splash zones, consolidation of porous & dusting surfaces, and primer or pre-treatment for subsequent epoxy or urethane deck coatings. Meets ASTM C881 (Type III. Grade 1. Class B & C.) and is VOC compliant (0 g/L).

    EP100 Epoxy Sealer

    EP100-SEAL HM

    EP100-SEAL HM is a high-modulus formulation of our EP100-SEAL epoxy healer/sealer product, making it an excellent option where minimal movement is desired to facilitate effective stress transfer, such as anchoring and doweling applications or structural crack repairs. Meets ASTM C881 (Type I, II, IV, V. Grade 1. Class C.) and is VOC compliant (0 g/L).

    EP100 Seal

    EP100-SEAL LM EPOXY SEALER/HEALER

    EP100-SEAL LM is a low-modulus formulation of our EP100-SEAL epoxy sealer/healer product, making it an excellent option where greater degrees of movement are required, such as bridge deck overlay applications where the material performs better if it is able to move along with the deck instead of cracking. Meets ASTM C881 (Type III. Grade 1. Class B & C.) and is VOC compliant (0 g/L).

    Epoxy Sealer

    EP-CLEARSEAL

    EP-CLEARSEAL is a two-component, moisture-insensitive, self-priming, impermeable, high-gloss epoxy sealer that exhibits excellent bond strength. EP-CLEARSEAL uses a cycloaliphatic amine curing system for color retention and chemical resistance making it ideal for sealing interior and exterior concrete floors and epoxy surfaces. By effectively penetrating and bridging moving cracks, EP-CLEARSEAL creates an impermeable seal on hairline cracks. It is also ideal to use as a top dressing for epoxy grout and chock installations or for locking in aggregate on the E-Chem EP-OVERLAY system. EP-CLEARSEAL is VOC compliant (0 g/L) and USDA Approved as an incidental food contact material.
